around 85 olms, I think if it reads above 120 it wont start, used resisters before on bad sensor to get comp running.

One was bad they had me add a resester to the bad one It fired up and ran good The other comp just stops at diferent times it might run a hour or two or it might run 10 min. I tightend every terminal I could find I will check in the morning if it stays runing Thanks

should be 75 ohms, but 85 is close enough

I called trane and they told me to use a 82 ohm resister and it worked thanks
